Here’s another angle for you. Nearly any male without severe physiological impediments, if he begins training in the right way at early enough of an age can run 2:30 or faster. This is the angle I would take for this. I don’t think anyone who runs 2:30 has no limits. I’d go from another angle and say there are very few young males who have limiting factors keeping them from running 2:30.
Good idea, i didnt know how to put it.. you put it how i was thinking 🙂
